ADJUSTABLE REST FOR HOLDING ELECTRIC LAMPS SUSPENDED.

SPECIFICATION forming part of Letters Patent No. 451,108, dated April28, 1891.

Application filed May 28,1890. Serial No. 353,115. (No model.)

To all whom it may concern.-

Be it known that we, CYRUs A. DANALS and WILLIAM O. PERRY, citizens ofthe United States, residing at Zanesville, in the county of Muskingumand State of Ohio, have invented a new and useful Improvement inAutomatic Adjustable Rests for Holding Electric Lamps Suspended in theAir, of which the following is a clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

Our invention relates to the suspension of electric lamps; and itsobject is to provide means for holding the lamp suspended in the airwithout having the weight of the lamp on the rope after the lamp hasbeen raised to its position and also to provide for the'easy ad- 3'ustment of the lamp to its position in the rest.

The invention consists of a pulley adapted to be attached to anysuitable elevated object, having depending therefrom and pivotallyconnected thereto a vertical bar, and to which swinging bar is pivotallysecured a hook-rest having the projecting arm or finger for tripping thehook in and out of engagement with the arm of the lamp in the raisingand lowering of the same.

The invention consists in certain novel features in the arrangement andconstruction of parts, all as hereinafter described. I

Referring to the accompanying drawings, Figure l is a side elevation ofthe electriclight hanger as suspended on the supporting wire or cable.Fig. 2 is a front view in eleva tion of the device.

In this invention the pulley A, which is provided with a shell forinclosing the same, and which shell forms the direct means for attachingthe hanging device to the supporting-cable and also provides thebearings for the shaft of the pulley-wheel, serves, together with therope, as the means for raising and lowering the lamp. The shell ispreferably formed of iron, as is the remainder of the device, and formsa jacket covering the entire pulley and protecting it greatly from thedestructive effects of damp weather. Pivotally secured to this shell andon the same shaft as that on which the pulley turns is the dependingswinging arm B, but which in this case is preferably formed of twosimilar bars, one

on each side of the shell or jacket and secured together at their ends,so that they are virtually one bar or piece. The pieces of metal whichform this depending arm are straight with the exception of a portion Jabove its pivot, which is bent or formed at an angle and may be weightedon its end, if necessary, as its sole object is to counterbalance thearm B when drawn out of its vertical position by the raising andlowering of the lamp to and from the hook O and by which the operationof adj usting the lamp is made certain and quickly performed.

To the lower end of the vertical swinging bar B is pivotally secured thehook-rest O, which is also formed after the manner of the dependingarmB, being formed of two hooks rigidly secured together and virtuallyforming but one, but having an advantage in this construction by givingtwo bearing portions tothe arm F of the lamp, so that it will besecurely held in a horizontal position.

Formed integral with the hook-rest O, or rigidly secured thereto at itspivotal connection with the bar' B, is the trip-finger I, by which thehook is released from the bail F when the bail comes in contact with thefinger in the raising of the lamp and engaged by the arm of the lamp inthe lowering of the lamp to the rest. 7 To this horizontal piece F,forming the arm of the lamp, is attached on each end the wire ll,supporting the lamp, and at the center of the arm is attached the rope Kfor raising and lowering the lamp. The rope passes up to and over thepulley, and thence down to any stationary object, where it is secured.

Having thus described our invention,what we claim, and desire to secureby Letters Patent, is-

l. A device for the suspension of lamps, consisting of a swingingdepending arm pivotally connected to a pulley-block adapted to beattached to an elevated object, said swinging arm being provided withthe counterweightarm and at its lower end with a hook-rest pivotallysecured thereto and having projecting arms, substantially asdescribed,whereby the hook-rest will be automatically tripped in and outof engagement with the lamp in the raising and lowering of the same, asset forth.

2. A device for the suspension of lamps, con-,

sisting of a shell or hood inclosing a pulley and adapted to besuspended on a suitable station ary object, the said shellorhood beingprovided with a depending swing-arm pivotally connected to said shell orhood and provided with the counterweight-arm and at its lower end with aswinging hook having the projecting arms for adapting the hook to betripped automatically in and out of engagement with the arm of the lampin the lowering and raising of the same, substantially as set forth.

3. In a device for the suspension of lamps, the depending arms B B,having the counterweightarms J J, pivotally secured to the hanger A andpivotally connected at its lower .end of said depending arm, as setforth.
